The recall covers Transitions Three-in-One Combination Booster Seats made from Dec. 18, 2014 through Jan. 29, 2016. The company says in government documents that the central front adjuster button that loosens the harness may be within a child's reach. If the harness doesn't fit snugly, that increases the chance of injury.

Evenflo says the problem only affects the seats when they're used as forward-facing harnessed boosters.

The company says no injuries have been reported. The problem was discovered in late January during Evenflo's analysis of consumer feedback.

Evenflo is notifying owners and will send a kit with a new seat pad and front adjuster assembly.
